MASSAGE DEVICE.

My invention relates to an improved massage device and has for its object to rovide clear, and exact specificaa hand-piece admitting of a series o differ-l ent operations by means of various instruments which may be attached and detachedin diierent ways. I attain this object by mechanism illustrated in the accompanying g drawings, wherein- Figure 1, is a longitudinal sectional view of my improved device. Fig. 2, shows a top view of a sleeve employed in connection with my device. Fig. 3, illustrates a detail sectional view of an eccentric fused in connection with -my device. Fig. 4, shows one means of securing. an instrument to the eccentric. Fig. 5, illustrates, in section, another form of sleeve used by me in connection with my device. Fig. 6, sho'ws another attachment used in my device. Fig. 7, illustrates another instrument which may be used in my device, with a different means of attachment.

Similar numerals indicate like parts in all of the drawings.

In Fig. 1, 1, illustrates a motor or source of power, 2, a flexible shaft, one end thereof being `connected to the motor and the other -to a steel shaft 3, by suitable connecting means 4, said steel shaft runningV through hand-piece 5, and partly through stationary sleeve 6, on suitableA bearings 7 the sleeve 6, being connected to the hand-piece 5, by means of a ferrule 8. The end of the -steel shaft running partly into the' stationary sleeve 6, lis screwthreaded as shown'at 9, so as to enter into the eccentric 10, (shown in detail in Fig. 3) andbeing of longitudinal contour and having an aperture 11, throughout its length; the lower portion being screw-threaded so; as to receive the screw-threaded portion of the steel shaft.3','

5 0 @and the upper end thereofA being c'onvexed and having a slot 12,' to hold the .instruments. The stationary sleeve 6, likewise has .a screw-.threaded o ening 13, for similar purposes. In this gure I have likewise shown a removable sleeve 14, to which is at- Specication of Letters Patent.

'with another means of attachment.

Patented Apr. 19, 1910.-

tached a brush 15, which may be slipped over the stationary sleeve vof my device and secured by suitable locking means as shown at 16. This sleeve is shown in detail in Fig. 2.

1n Fig. 4, I have illustrated a cup-shaped iieXible bristle-bearing fan 17, the bristles of which are caused to iex or flare outwardly by the centrifugal force caused by the rotary motion of the instrument when in operation, thereby producing a strong current of air, together with its means of attach.- ment to the eccentric employed in my device, which is accomplished by securing a spindle or shaft 18, having a lug 19, to the instrument sought to be attached and then inserting this shaft into the. aperture 11, of the eccentric, so-that the lug 19, of the shaft slides along the slot 12,. of the eccentric, when the slot of the eccentric into which the vlug slides will tend to hold it in place.

. In Fig. 5, I have shown another sleeve 20, differing-fromthat shown in Fig. 2, inl that a number of applicators may be detachably connected to .this` sleeve as shown at 21, 22',

and 23, which may be usedalternately. This sleeve may be secured to the stationary sleeve 6, in any suitable manner, 'as shown'in Fi f. 2.

Fig. V6, lshows a detail view vof another instrument 20, and its means lof -attachment to the eccentric.

Fig. 7, shows still another instrument 24,

In 1nstruments of this nature the means of attachment is formed of a small screw-threaded plug 25, which enters into the screwthreaded opening 13, of the stationary Vsleeve 6.

From the foregoing description the operation of my device will be readily understood.

In my device both classes of massage 1nstruments can be used to advantage, namely,

o1' provide them with a screw-threaded plug to enter into the screw-threaded opening of the stationary sleeve.

It is obvious that many changes and modifications may be made in the construction of my device, Without departing from the spirit of my invention and I do not intend to limit myself to the specific construction as shown, but

What I desire to secure by Letters Patent is:

1. A massage device comprising a handpiece, a casing secured to said hand-piece, a spindle Within said casing having an elongated eccentric operatively connected thereto for imparting vibratory motion to said casing and a sleeve removably secured to said casing having a series of applicators secured thereto.

2. A massage device comprising a handpiece, a casing, a sleeve having apertures longitudinally therein for the reception of applicators removably mounted upon said casing, said sleeve and casing provided With a screw-threaded a erture at a point farthest from the han -piece, a spindle Within said casing carrying a slotted elongated eccentric, an appllcator having a splndle and lug mounted thereon for engagement with said eccentric.

3. A massage device comprisin a handle having suitable bearings, a spin le carried in said bearings, a flexible shaft connected to said spindle and to a source of rotary motion,v a vibrator member attached to said spindle and having its center of gravity eccentric to its center of rotation and a cupshaped rotatable flexible bristle'bearing fan in operative connection with said vibratory member;

In testimony whereof I have hereunto set my hand in the presence of two subscribing Witnesses.
